Anxiety is a common emotion. People experience different levels of anxiety in different situations and try to prevent adverse situations that cause anxiety and actively engage in anxiety-reducing activities as a protective response. When the severity of anxiety is disproportionate to the objective event or situation or lasts too long, it is pathological anxiety, clinically known as anxiety symptoms. Anxiety symptoms are manifested as psychiatric and somatic symptoms. Psychiatric symptoms refer to an internal experience of anxiety, fear and apprehension accompanied by nervousness; somatic symptoms are accompanied by symptoms of autonomic nervous system hyperfunction on top of psychiatric symptoms, such as palpitations, shortness of breath, chest tightness, dry mouth, sweating, muscle tension tremor, trembling or flushing and pallor of the face. Anxiety disorders are among the most common mental disorders. According to the WHO survey, the lifetime prevalence of anxiety disorders in the population is 13.6%-28.8%, and the annual prevalence is 5.6%-19.3%. Five major risk factors associated with anxiety disorders have been identified: 1. family history of anxiety disorders; 2. history of childhood or adolescent anxiety disorders, severe shyness, early poor educational practices; 3. stressful life events or traumatic events, including abuse; 4. female, unmarried, divorced, widowed, low education, unemployed, low income; 5. co-morbid psychiatric disorders, especially depression. There are many psychological treatments for anxiety and fear, but cognitive behavioral therapy (CBT) is still the most widely used, simple, practical and recognized as effective. Many national guidelines for the prevention and treatment of disease have made the combination of medication and psychotherapy the first line of recommended treatment. The principles of psychotherapy for anxiety and fear include: 1. dealing with anxiety symptoms, such as relaxation and biofeedback; 2. dealing with fear or fear disorders, such as relaxation and exposure (overcoming avoidance behaviors); 3. changing inappropriate anxiety perceptions, such as catastrophizing thinking; 4. learning to patiently, carefully and attentively “look through the symptoms to understand the patient’s true internal experience or conflict “. In conclusion, we need to know that anxiety and fear are normal human emotional reactions in a particular situation and are protective responses to our adaptive environment. In most cases, what affects us the most and causes us to be unhappy is not so much the anxiety and fear itself, but rather our “anxiety about anxiety”, i.e., the cognitive level of the problem. Our ultimate goal is to live a better and happier life during our lifetime, so the ultimate goal of treatment for anxiety and fear is not so much that we overcome it, but that we accept it; it is not so much that we overcome it, but that we learn to live with it. Believing in ourselves, we have the ability to conquer and transform the world, and we must also have the ability to reacquaint ourselves with and re-examine ourselves, so that we can dance with the world.
